In short, in 1972 when Leakey found a skull that is between humans and apes, he reconstructed it by hand using the best knowledge available at the time.

It's important to baraminology to see the change. Now it can be considered to be "all ape" instead of "all human" (with rickets or something).

And baraminology fits in the big tent and even beyond. I mean, poor ol' Sternberg isn't a creationist or IDist, just a man interested in fairness, and he belonged to a baraminology group. We really do need to know which hominin fossils are all ape and which are all human.
